1. Introduction When we visit a website, we usually do so via a URL, such as accessing Baidu through the domain: www.baidu.com. After entering the domain in the browser, the communication ultimately resolves the domain to the corresponding IP address, and communication is conducted at the lower level based on the IP. We don’t need … Read more
This experiment uses a homemade voltage and current sensor. The sensor collects voltage and current values, displays them on the screen, and simultaneously sends them to a computer via Bluetooth for data processing. Through linear fitting tools, the resistance value is obtained, and the measured values are equal to the real values within an acceptable … Read more
Introduction As climate change becomes increasingly severe, people’s attention to weather conditions is also growing. More and more individuals are attempting to install weather displays at home to stay updated on local meteorological information. This solar-powered electronic paper weather display perfectly meets this demand, with an ultra-small size that can be seamlessly integrated into window … Read more
